Three outstanding results are reported: (1) The superconductivity-induced modification of the far-infrared conductivity of an iron\u003cbr\u003earsenide with minimal chemical disorder is quantitatively described by means of a strong-coupling theory for spin\u003cbr\u003efluctuation mediated Cooper pairing. The formalism developed in this thesis also describes prior spectroscopic data on more disordered compounds. (2) The same materials exhibit a sharp superconductivity-induced anomaly for photon energies around 2.5 eV, two orders of magnitude larger than the superconducting energy gap. The author provides a qualitative interpretation of this unprecedented observation, which is based on the multiband nature of the superconducting state. (3) The thesis also develops a comprehensive description of a superconducting, yet optically transparent iron chalcogenide compound. The author shows that this highly unusual behavior can be explained as a result of the nanoscopic coexistence of insulating and superconducting phases, and he uses a combination of two complementary experimental methods - scanning near-field optical microscopy and low-energy muon spin rotation - to directly image the phase coexistence and quantitatively determine the phase composition. These data have important implications for the interpretation of data from other\u003cbr\u003eexperimental probes.\u003cbr\u003e\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45279954534551,"sku":"9783319377520","price":7345.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9783319377520.webp?v=1769294995","url":"https:\/\/atlanticbooks.com\/products\/charge-dynamics-in-122-iron-based-superconductors-9783319377520","provider":"Atlantic Books","version":"1.0","type":"link"}
